Xylorimba

The xylorimba (sometimes referred to as xylo-marimba or marimba-xylophone) is a pitched percussion instrument corresponding to a xylophone with an extended range (and not to a combination of a xylophone with a marimba, as the name might suggest).

Like the xylophone and marimba, the xylorimba consists of a series of wooden bars laid out like a piano keyboard "with a compass sufficiently large to embrace the low-sounding bars of the marimba and the highest-sounding bars of the xylophone."
